This short documentary shows what life next door to a coal ash pit is like. Residents in Dukeville, next to Duke Energy's Buck Steam plant, have been afraid to drink their well water since testing last year showed known carcinogen hexavalent chromium in their wells.

Contaminated waste from a retired coal plant in Rowan County, North Carolina, has been found leaking into a tributary of the second largest river in the state, environmental groups charged on Thursday.

CBS news program 60 Minutes will run a segment on coal ash Sunday focusing on Duke Energy and developments in North Carolina, including interviews with CEO Lynn Good and environmental critics of the company.

The controversy surrounding Duke Energy's coal ash ponds is hitting home with some neighbors who say recent test results have them scared to drink their own well water. Sherry Gobble, her husband Bryant and their son and daughter live in the Dukeville community near coal ash ponds behind the Buck Steam Station near Salisbury.

Since 2011, Duke and North Carolina environmental regulators have known that groundwater samples taken from monitoring wells near the Thomases' home and others in Dukeville contained substances — some that can be toxic — exceeding state standards.

Duke Energy was recently required by the state to monitor ground water around the perimeter of three unlined coal ash ponds at its Buck power plant. They have submitted ground water monitoring well data to the state of NC since 2006. Between 2006 and 2013 there were a total of 327 exceedances of the NC groundwater standards at Buck.

A Wake County Judge today ruled that Duke Energy must take immediate action to eliminate the sources of groundwater contamination that are currently violating water quality standards at all 14 of its coal-fired power plants in North Carolina.
